Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Should 'Hi', 'thanks,' taglines, and salutations be removed from posts?

So you're not supposed to start questions with "Hello guys" or end them with a signature, right? Well, here's an idea: Detect common cases of this and warn the user that this is unwanted cruft.

So, if your question starts with:

  • hello
  • hi
  • hey
  • etc.

...or ends with:

...then a box pops up that says:

Your question starts with "hello". This is considered unnecessary; please remove it.


Your question ends with your username. You do not need to "sign" your questions; please remove it.

...and so on. It shouldn't be blocking, just informational.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

Hmm... I wouldn't usually vote to close as dupe because of an answer, but since this is an Official Canonical Jeff Answer, I guess it qualifies for an exception. Nice, @JoshCaswell. – Pops Jul 16 '12 at 15:20
@Popular: The Jefficial answer still counts for something, huh? I figured random would just start erasing history around the beginning of the month. Eventually there'd be a Meta question: "Why is there no user #1?" – Josh Caswell Jul 16 '12 at 16:44

Greetings like this are actually already filtered out automatically. There is a regex which checks for the presence of things like that at the beginning of a post and just strips them out silently when it's posted. It does not for signature sorts of things at the end though:

The thanks parts at the end of posts are much more difficult / risky to detect, so we are not touching those for now.

Thanks @KevinVermeer, I was looking for that post but couldn't find it. I edited that into the answer. – nhinkle Dec 6 '11 at 20:19
